I would like to add, point density to be affected by weight painted vertex group as well as a texture (for instance cloud texture).

I can use vertex group as density influencer on point distribute node by writing the name of the vertex group on density parameter (ground.camPosition) as above: enter image description here I can use texture with attribute texture sample node: enter image description here

However, I cannot combine them how can I combine vertex group and texture for combined density maps on geometry nodes?

Thanks in advance

With Blender 3.1 (GN-Fields) ...

  • Create this node tree

enter image description here

  • Weight Paint something ... it will automatically generates Vertex Group by default named Group

enter image description here

  • With Group Input node selected go to Modifier Properties and next to the Value click on "spreadsheet" icon and choose your vertex group (here named Group) or type it into the field.

enter image description here

So ... in this case is texture mixed with vertex weight by Math node

Note: If you have difficulties to set vertex group attribute in modifier ... go to Geometry nodes editor > Side panel N ... there should by set type Float (it happens when plugged Math value) ... if there is something else switch to Float (Vector worked too).
